Adding Set-MailboxSentItemsConfiguration / Get-MailboxSentItemsConfiguration for Exchange 2013, which is more elegant and manageable than setting (version-dependent) Outlook registry keys.
Just like the EMC (Exchange Management Console) in Exchange 2010. That had the ability to preview the Exchange Management Shell syntax or in other cases to review the used syntax after it was applied.
This ability is a great learning tool but also a valuable tool for documentation.
When a user leaves the organization and their mailbox and AD account are removed the delegate information get's stuck in the Outlook client and creates errors for the users until it is removed. Is there anyway to make this a function of AD or Exchange so that this removed when a user leaves?
DIR 2.0 has added more functionality especially when combined with single item retention except for the ability to restore users deleted folders. If a user deletes a folder with items in it, we can only restore the items and not the folders WITH the items in it. In 2013, New public folders have the ability but not normal mailboxes.
